Much-Anticipated 'Gone Girl' Trailer Finally Debuts! (VIDEO)

The highly anticipated Gone Girl trailer debuted Monday, giving fans a peek at the thriller that promises to be every bit as intense as the best-selling Gillian Flynn novel upon which it's based.

Set to a haunting cover of the Charles Azvanour song She, the film appears to be entirely true to director David Fincher's dark style, and from the looks of it, elicits a standout performance from Ben Affleck, who plays Nick Dunne, the man suspected of killing his missing wife Amy (Rosamund Pike).
